ODF1.2 defines 15 standard symbols for charts. As earlier mentioned, I
try to implement the missing ones. But there are some problems with the
symbols "horizontal-bar" and "vertical-bar".
The implementation of the current symbols in
/calc/chart2/source/view/main/ShapeFactory.cxx in method
createPolyPolygon_Symbol draws the symbols in a way, that the given size
in parameter rSize is completely used. Moreover, this method is called
with a square in rSize in all default cases.
I have tried now this way for a "horizontal-bar": Draw a rectangle,
which is 1/5 of the given height. With this attempt I get correct
symbols in the chart itself and in the legend. But the preview in the
data series dialog or in the data point dialog paints my
"horizontal-bar" and my "vertical-bar" as square. And in the list in the
pop-up menu my bars are shifted.
As far as I see, the graphics to be used in the dialog are generated in
components/cui/source/tapages/tpline.cxx. My idea is now to insert a
100% transparent square into the temporary page pPage and mark that
object together with my symbols for generating the bitmaps.
For inserting an additional object, I have used
in IMPL_LINK( SvxLineTabPage, MenuCreateHdl_Impl, MenuButton *, pButton )
after line 1540 and
in line 1552 seems to work too.
But I do not know how to make the object transparent. Especially, I do
not know how to use these "itempool"-thing. In Basic I would have
assigned a value to the property. But in C++ I'm totally lost. Do you
can point me to a guide or lead me to a solution?
